Girard-Perregaux Sea Hawk II Pro
The Sea Hawk II Pro is a wristwatch by Girard-Perregaux.
The model Sea Hawk II Pro 3000 m is a professional diving instrument, which can withstand the pressure up to 3,000 m. As with all Sea Hawks, the case is immediately recognizable by the crown attached at 4 o'clock and the rotatable bezel.
The caseback of the Sea Hawk II Pro has a special symbol: a bottlenose dolphin that winds around an anchor with three-cornered hat. This symbol is associated with a patent, that Girard-Perregaux filed 1898 at the German Patent Office.
